摘要

针对现有虚拟化云无线接入网络资源利用率低、能耗高、用户服务质量无法得到保证等问题，提出一种带有混合能量供电的能耗感知虚拟化资源分配机制。根据不同网络设备的能量来源和能量消耗情况，建立能量到达模型和能量消耗模型；进而，在保障用户服务质量的前提下，考虑比例公平和能耗优化，利用异步更新的分布式算法对不同类型虚拟云无线接入网和用户虚拟基站分配资源和能量，从而有效提高网络能量效率。仿真结果表明，所提资源分配机制能够降低能耗，同时有效地减小了时延，提高了吞吐量。

Abstract

Aiming at the problems of low resource utilization rate

high energy consumption and poor user service quality in the existing virtualized Cloud Radio Access Network

an energy-aware virtualized resource allocation mechanism with hybrid energy supply was proposed.According to the energy sources and energy consumption of different network devices

energy arrival and energy consumption models were established.Furthermore

under the premise of guaranteeing the quality of user services

considering proportional fairness and energy consumption optimization

distributed algorithms based on asynchronous update were used to allocate resources and harvested energy for different types of virtual cloud radio access networks and user virtual base stations to effectively improve the energy efficiency of network.The simulation results show that the proposed resource allocation mechanism can reduce energy consumption while effectively reducing the latency and improving the throughput.
